Popis:	The aspiration of excess numbers of follicles was examined as a method for inducing twin pregnancy in cattle. Seven cattle were administered follicle stimulating hormone (FSH) for superovulation. The number of follicles was measured by an ultrasound scanning scope and excess numbers of follicles were punctured and aspirated to decrease the number of ovulations. One or two follicles were left intact in each ovary. Two of six cattle responding to FSH bore twins and one pair of twin calves was born.
